+AVS to BluRay SUP/PGS and BDN XML
+---------------------------------
+
+This program can be used to transform AviSynth scripts, which produce RGBA
+output, to BDN XML+PNG format. This in turn can be transformed into a SUP file,
+which can be used to master a BluRay disc with subtitles.
+
+Usage instructions:
+
+0. If you want to build it:
+     i586-mingw32msvc-gcc avs2bdnxml.c -o avs2bdnxml.exe -lpng -lz -lvfw32 \
+       -Llib/ -O3 -Iinc/
+
+1. Prepare subtitles. You can either produce subtitles in a normal format like
+   SRT or ASS/SSA, or produce an RGBA video beforehand.
+
+2. Create an AviSynth script. If you made a regular subtitle file, you can use
+   something like this:
+
+     video=AviSource("video.avi")
+     # This requires at least VSFilter 2.39
+     MaskSub("subtitles.ext",video.width,video.height,
+             video.framerate,video.framecount)
+
+   If you created an RGBA video, do something like this instead:
+
+     AviSource("subtitles_RGBA.avi")
+     FlipVertical()
+
+3. Run the program:
+     avs2bdnxml input.avs Undefined und 1080p 23.976 output.xml
+
+4. For some programs, you have to convert the PNG files to 8bit RGBA palette.
+   This doesn't apply to BDSupEdit. You can do it with a tool like pngquant or
+   pngnq.
+
+     pngquant: http://www.libpng.org/pub/png/apps/pngquant.html
+     pngnq:    http://pngnq.sourceforge.net/
+
+5. You get a BDN XML file in the following format:
+
+     <?xml version="1.0" encoding="UTF-8"?>
+     <BDN Version="0.93" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
+     xsi:noNamespaceSchemaLocation="BD-03-006-0093b BDN File Format.xsd">
+     <Description>
+     <Name Title="Undefined" Content=""/>
+     <Language Code="und"/>
+     <Format VideoFormat="[ 480i / 480p / 576i / 720p / 1080i /1080p ]" FrameRate="[ 23.976 / 24 / 25 / 29.97 / 50 / 59.94 ]" DropFrame="false"/>
+     <Events LastEventOutTC="00:00:00:00" FirstEventInTC="00:00:00:00" ContentInTC="00:00:00:00" 
+     ContentOutTC="00:00:00:00" NumberofEvents="[ number of encoded frames ]" Type="Graphic"/>
+     </Description>
+     <Events>
+     <Event Forced="[ False / True ]" InTC="00:00:00:00" OutTC="00:00:00:00">
+     <Graphic Width="0" Height="0" X="0" Y="0">000000.png</Graphic>
+     </Event>
+     </Events>
+     </BDN>
+
+6. Use a program like BDSupEdit or BDSup2Sub to convert the BDN XML
+   to a BD-SUP file. The rest is left as an exercise for the reader.
